Definition

给以, 加以, and 予以 all are Verbs, and 加以 also be a Conjunction, which all means [give; grant].

Example

给以, 加以, 予以 (Verbs), plus a disyllabic verb as the object indicates what the disyllabic verb means. All three words are literary, with 予以 the most literary, 加以 next, and 给以 the least.
1) In the examples above, the 给以, 加以, 予以 are interchangeable, but the literary flavor is different;

2) The disyllabic verb that follows must have a meaning of "disposal ".Otherwise, the verb cannot be used. e.g, one cannot say 给以/加以/予以) 喜欢, because 喜欢 means "a natural state of mind" and has no meaning of "disposal";

3) All these sentences can do without 给以, etc. but if so, they would not sound as literary or formal as the former ones. Furthermore, 给以, etc. cannot take a very colloquial disyllabic verb as the object, e.g. one cannot say 给以/加以/予以) 打算;

4) Sometimes 加以 and 予以 can take disyllabic verb objects (such as 除霜 defrost, 结账 check out/settle accounts, 判刑 pass a sentence on a convict, etc).
